This series implements virtio-scsi queue steering, which gives
performance improvements of up to 50% (measured both with QEMU and
tcm_vhost backends).
This version rebased on Rusty's virtio ring rework patches.
We hope this can go into virtio-next together with the virtio ring
rework pathes.

This will be needed soon in order to retrieve the per-target

This patch adds queue steering to virtio-scsi. When a target is sent
multiple requests, we always drive them to the same queue so that FIFO
processing order is kept. However, if a target was idle, we can choose
a queue arbitrarily. In this case the queue is chosen according

Avoid duplicated code in all of the callers.

virtio_scsi_target_state is now empty, but we will find new uses
for it in the next few patches. However, dropping the sglist lets
us turn the array-of-pointers into a simple array, which simplifies
the allocation.
However, we do not leave the virtio_scsi_target_state struct

Hi All
I would like to attend LSF/MM and talk with people about scsi and iscsi testing.
I am the author/maintainer for libiscsi which is userspace initiator
used primarily by KVM/QEMU.
This package also includes a pretty big test suite for mainly SCSI but
also a lot of interesting iSCSI tests.

This replaces a call to kmalloc() followed by memset() with just one
call to kzalloc(). This was found using make coccicheck.
